- coim'm'nn TYPE-WRITING AND nrroun'r-ns'rrnc MACHINE.

To all it concern."

Be it known that I, GLENN. J. Barnum,-

York, have invented certain new and useful I Improvements in Combined Type-Writing and Amount-Listing Machines,.of which the following is a specification.

' The chief object of the present invention is to provide for visible writing after the manner of the so-called front strike typewriting machines while at the same time providing for the printing of an amount on the same horizontal line that the visible writing follows, by causing the paper to face a different waywhen receiving amount imprints from the way in which it faces when receiving typewriter imprints. Thus, when the familiar typewriter roller platen is employed in an embodiment of the present invention, it will present the paper facing toward the front to receive the type-written imprints, whereas when the listing department of the machine is operated this roller platen will turn so as to present, facing downward, that portion of the paper along which the typewriting has been done; then at the conclusion of the amount printing operation the roller platen will return to its original position again presenting the printed portion of the paper facing toward the front. It will be seen that this arrangement permits of both typewriting and amount printing mechanisms being confined within the lateral limits'of an ordinary typewriter or an ordinary adding machine for these mechanisms are not required to be arranged side by side but one can be in the rear of the other and the key-board of one can correspondingly extend in rear of the key-board of the other. F or example, the ordinary typewriter key-board can occupy its usual position at the foremost part of the machine while the adding machine keyboard can intervene between said typewriter key-board and the type-basket of a front strike type-writing mechanism, the type-carriers of the amount printing mechanism being located in rear of said basket and the type-bars thereof. Thus within practically the compass of an ordinary addmg machine, a combined type-writer and adding machine may be embraced and the key-board of each played with as much Specification of Letters Patent. Application filed December 4, 1908. Serial No. 348,279.

facility as similar key-boards of either the ordinary type-writer or the ordinary adding machine.

With the above stated and incidental ob- I and a preferred form of embodiment of which is described in detail hereinafter and whereof are recited in the appended claims fully illustrated in the accompanying drawings forming part of this specification.

Of said drawings Figure .1 represents in plan view a machine embodying the invention; Fig. 2 represents said machine principally in right side elevation, the supporting frame-work and part of the amount keyboard appearin in section; Fig. 3 represents said mac inc in left side elevation with frame-work in section; Fig. 4 represents the machine in rear elevation with the casing panels removed; Fig. 5 represents a vertical cross-section of the machine taken just in front of the typewriter basket, and

looking toward the rear but omitting a number of parts whose appearance in crosssection would serve no useful purpose in this view; Fig. 6 is a somewhat similar sectional view thereof taken on a line farther to the rear and not including the lower part of the machine nor carried quite to the sides thereof; Fig. 7 is a fragmentary section from front to rear of the machine taken at about the middle of the same and embracing the typewriter basket and part of the amount printing mechanism; Fig. 8 is a right side elevation of the super-structure of the machine which includes the roller platen and appurtenances; Fig. 9 is a sectionalized left side elevation of the same parts, the roller platen being shown in dotted lines as the section is taken beyond the same; Fig. it) isa top plan view partly in'section of certain of the parts appearing in side elevation in Fig. 9; Fig. 1l represents in side elevation that portion of the machine having to do morelespeeially with the actuation of the ammint types; Fig. 12 represents a cross-section taken on the line 1212 of'Fig. 11; and Fig. 13 represents an alining and guiding comb deta hed in plan view,

Referrmg first to 1 the reference numeral 1 designates the skeleton castings of the supporting frame-work and inclosing casing of the machine, the same being formed to provide panels after the usual style in this class of machines. In the present instance provision is made for two key-boards, one at the very front of the machine with keys bearing the usual typewriter inscriptions and another in rear of this typewriter keyboard with keys arranged in parallel rows and numbered from one to nine in each row after the manner of the usual adding machine key-board. Both key-boards rise as they extend rearwardly and in the present instance the general plane of the amount keyboard is higher than that of the typewriter key-board partly to sufliciently separate the two key-boards to prevent touching the keys of one whileoperating the other and partly for the purpose of exposing to view at a convenient place the adding or indicating wheelsor dials which show the results of operations of the adding or amount printing or listing section or department of the machine. For this latter purpose the castings of the frame-work and easing provide a reentrant portion 2 (Fig. 2) extending across the machine between the two key-boards with a sight opening in the bottom covered by glass 3 immediately over the adding or indicating wheels 4. In rear of the amount key-board the casing and frame-work is elevated to properly support the type-basket 5 which may be of the usual form designed to accommodate the type-bars 6 lying horizon tally with their typefacing upward. This portion of the frame-work also supports typewriter ink ribbon.spools 7 the ink ribbon passing through suitable upright guides 8 whereby it is properly disposed in front of a roller platen 9. The latter carries trunnions 10 resting in suitable hearings in the side pieces 11 of a laterally shifting carriage such as commonly employed in typewriting machines. In the present instance the trunnions of this'roller platen also have hearings in the side plates 12 of a cradle which is adapted to rock in the laterally shifting carriage. This cradle is completed by crossrods 13 and 14 which connect the side plates 12 and support certain well known roller platen appurtenances such as paper guides and feed rollers. The cross-rod 13 is preferably uare in cross-section and on it is mounted a siding block 15 carrying the resilient arms 16 and 17, the latter constituting p'aper guides and the former supporting a comparatively short feed roller 18. This structure is used when a narrow strip of paper is employed as common in adding machines when simply listing amounts. The cross-rod 1% carries arms 19 which support between them long feed roller 20 suitably springpressed against the platen roller 9 and serving as in the ordinary typewriter to feed a wide sheet of paper. This cross-rod 14 also carries an arm 21 having a roller 22 engaging the corrugated periphery of a ratchet disk 23 on one end of the platen roller'9.- A spring 24 connects the outer 'end of said arm 21 with one of the side plates 12 of the cradle so as to press the roller 22 against the corrugated periphery of the disk 23 with suflicient force to accomplish the usual result of holding the platen roller at the different positions 1t takes up in the line spacing. In the present instance another function is allotted to this a'lining device, viz., that of establishing. a frictional connection between the platen roller and its cradle whereby the rocking of the latter with the journal of the platen roller as a center will result in turning said roller. In carrying out the principal object hereinbefore mentioned said cradle is rocked to such extent as to move the platen roller through an arc of ninety degrees so that the portion of the roller serving as a platen for the front strike of'the typewriter keys will be carried downward and rearward 'to a substantially horizontal position above the amount printing typecarriers.

The reference numeral 25 designates the usual handle lever pivoted upon the sliding carriage 11 and adapted to serve the double purpose of returning the carriage to the right and turning the platen roller for line spacing through cooperation with the crownratchet of the disk 23 in a well known manner. The carriage 11 carries the usual rack 26 meshing with a spring-impelled pinion 27 clutched to an escapement wheel 28. The usual escapement pallet 29 is employed to bring about the step by step movement of the carriage toward the left in typewriting, said pallet beingoperatively connected with a space bar 30 at the front of the typewriter key-board and also with the key-operated type-driving devices. The connectlon between the escapement pallet and said space bar is accomplished through the medium of a long link 31 and a bell-crank lever 32. The character keys of the typewriter mechanism are designated by the numeral 33 and they are connected through bell-crank levers 34 and links 35 with cross-heads 36 mounted on radius links 37 and held by springs 38 in normal rearward position. The typebars 39 are connected through links 40 with said cross-heads 36 so that when the keys are struck the type-bars will be swung upwardly through an arc of ninety degrees, striking the ink ribbon from the front in the usual manner to make an imprint upon the paper where it lies over the front of the platen roller. Suitable mechanism will be employed to shift the ink ribbon as a result of striking the typewriter keys and to reverse the direction of movement of the ribbon when it has been unwound from one s 001 7 but these devices form no part of tlie present invention nor is a description of them at all necessary to a complete understanding of the present invention. Consequently no detailed description of such dew vices-will be given herein. Enough has been pointed out with reference to the typewriting section or department of the machine to show that it will operate as any ordinary typewriter.

The type for printing amounts is in the form of short bars 41 slidingly mounted in sets of five upon sector plates 42, there being one of these sets of type-bars for each row or bank of amount keys 43. Reference may be had to the patent to William S. Burroughs No. 505,078 for the details of this character of type-carriers. The sector plates 42 are mounted to swing upon a cross-shaft 44 and'each is formed with a depending arm 45 connected by a bent link 46 with a rack 47 mounted to slide between guide plates 48 carrying antifriction rollers 49 in engagement with the edges of the racks. Each rack has an upstandlng projection 50 and the amount keys 43 are connected with rods or wires 51 having laterally bent lower ends occupyin vertical slots in the guide plates 48 and adapted to present stops to the projections 51$for limiting the movements of .the racks 47 1 according tothe denomination of the key depressed. The sector plates 42 stand normally in rearward position'with zero types at the rinting line. It will be seen that rearwar movement of the racks 47 through the connections described will permit forward swinging of the sector plates and consequently the advance of numeral types to the printing line. Springs 52 coupled to the arms 45 and the base. of the machine tend to draw said "arms rearwardly and consequently swing the sectors for wardly. Such movement of the sectors is, however, normally prevented by the engagement with the rear edges of the arms 45 of a cross-bar 53 carried by arms 54 secured to the shaft 44. This cross-bar and its supporting arms constitute a restoring frame or bringing the type-sectors back to normal position at the conclusion of an operation whereas at the outset of an operation this frame will be swung rearwardly so as to permit advance of any of the type-sectors.

An arm 55 secured to the shaft 44 extends forwardly and carries a roller 56 in engagementwith a cam-slot 57 of a plate 58 secured to a shaft 59. The latter has secured to it another plate 60 connected through a link 61 with a crank arm 62 secured to a rock-shaft 63 to which an operating crank handle 64 (see dotted lines, Fig. 2) is attached. The form of the ca1n-slot 57 is such that upon drawing forward the operating handle 64 the frame composed of the arms 53'? and the cross-bar 53 will be swung rearwardly. This removes the obstruction to rearward movement of the typesector arms 45 and in those banks where amount keys have been depressed the type sectors advance until the projections 50 of the racks 47 encounter the bent ends of the stop rods or wires 51. Of course in banks where no keys have been depressed there should be no such advance of the type-sectors. To prevent movement thereof notwithstanding the retreat of the restoring frame, a series of latches 65 are employed, the same being pivoted intermediate their ends to the plates 48 and normally engaging at their forward ends in notches 66 of the racks 47. It will be seen that engagement of the abrupt forward ends of these notches with the front ends of the latches will prevent rearward movement of the racks so long as the latches remain in their normal position. Preponderance of weight on the front side of the pivots of these latches will suffice to engage them with the notches but s rings may be employed for 90 of bell-crank levers whose longer arms 69 protrude through slots in detent plates 70 for the several banks of keys. Each of these detent plates is formed with a series of inclined portions 71, one for each key, and with slotted horizontal portions 72 through which the keys extend. Each key-stem has an inclined slot 73 normally in alinement with the associated inclined portion 71 of the detent plate. It will be seen that depression of any key will therefore result in sliding the detent plate rearwardly. This in turn swings the long arm 69 of the aforesaid bell-crank rearwardly and its short arm downwardly thereby depressing the rear end of the latch 65 and disengaging its front end from the notch of the rack 47 The stems of the keys are under-cut where the inclined slots are formed and the undercut is carried beyond the slots so that when the detent plate is moved rearwardly by the depression of any one of the keys all the other keys are locked against depression by reason of the inclined portions 71 of the detent plate passing rearwardly beyond the slots of these unoperated keys. The keystems work through slots in horizontal plates 74 and 75 and are normally upheld by springs 76 connecting the lower ends of the key-stems with'the plate 75. The detent plate is caught and held in its displaced position by a latch 77 pivoted below said plate 75 and formed at its forward end to "drop over a lip 78 of the bell-crank arm 69 shortly after the latter has started re rward. This latch 77 is extended in rear of its pivot and provided with a handle 78 pro ecting up and at the lower end of this extension a flip pawl 80 held by a spring 81 against a stoppin'82. A lever 83 pivoted intermediate its ends to the supporting frame-work of the machine carriesa roller 84 at its forward end over which roller said flip pawl rides when the operating handle is drawn forward. When the operating handle moves backward to normal posit-ion the flip pawl 80, prevented from turning by the stop-pin 82, acts against the roller 84 and rocks the lever 83. This lever on the rear side of its pivot is- (mupled to a link 85 which is in turn coupled to a bell-crank lever 86. The latter is secured to'a pivot rod 87 which extends across the machine and carries another arm similar to the upstanding portion of the bell-crank lever 86 between which and said arm extends a rod 88 Each of the latches 77 is formed with a depending finger 89 overlying the front side of said rod 88. It will therefore be seen that when the lever 83 is rocked in the manner described the rod 88 will lift, all of the latches 7 7 and thus permit the detent plates 70 to be restored to normal position as the depressed keys rise under the influence of their springs. Of course the detent plates themselves may be drawn forward by springs if esired.

From the above description it will be clearly understood how the type -carriers 1 take up positions to present at the printing line type corresponding with the keys-which have been depressed, zero ty es being of course presented in banks wiere no keys have been operated. An inking ribbon extends between the type at the printing line and the platen roller 9, this inking ribbon being carried by spools 90 and shifted step by step in the operations of the machine through devices which need not be described in detail in this specification. In furtherance of the design of turning the platen roller through an arc of ninety degrees when amountprinting is to be done the following connections are employed. There is secured to the rock-shaft M a short arm 91 to which is jointed one end of a link preferably composed of two telescoping members 92 and 93 held together by a spring 94: The other end of this link-is coupled to an upstanding prog'ection 95 ofone side bar 96 of a frame including a rock rod 97 extending across the and another side arm 98 at the opposits side of the machine ig. To the Otherwise the re- 7 forward ends of the side-bars 96 and 98 of this frame arefjoined the lower ends of a yoke 99 which extends up into the laterally shifting typewriter carriage 11 and is formed therein as a hanger (see dotted lines at 100, Fig. 8) supporting a roller-101 riding upon" the cross-rod 102 of a rocking frame completed by side-bars 103 pivoted on studs of the carriage 11. One of these sidebars has a projecting arm 104 giving it a bell-crank form and this arm 104 is oined to a pitman 105 which at its forward end carries a pin 106 extending through an areshaped slot 107 in the'side plate of the carriage, being headed over said slot as shown at 108 in Fig. 10. Said pin on the opposite side of the pitman 105 enters a notch .109 in the under-edge of one of the side plates of the platen cradle.

It will be seen that through the connections described the forward rocking of the shaft 44 produced by forward movement of the operating handle 64 results in drawing down theframe composed of the side arms 96 and 98 and cross-rod 97 so that the yoke 99 is lowered and in consequence the frame 102103 swung downwardly and the arm 10% rocked rearwardly drawing the itman 105 with it'and thus turning the era le and the platen to the desired extent. In this manner that portion of the paper overlying the platen roller, which portion was presented to the t pewriter action, will be carried down an rearwardly and brought to the proper position for receiving an imprint from the amount types. In order to prevent rocking, of the cradle by the turning of the platen roller in the customary typewriter adjustments, the pitman 105 is formed with a rearward extension 110 which normally extends in front of a square lug 111 on the inner side of one of the carriage side plates as shown in Fig. 9. Where the pitman is coupled to the crank arm 104 it is formed with an oblique shit 112 the sides of which have a cam action in conjunction with the 1n 113 of said crank arm so that when the atter swings rearwardly the extension 110 of the pitman will be lifted above the stoppin 111. .Thus only through the medium of the crank arm 65 can the cradle be rocked.

The devices for causing the amount types to impinge against the ink ribbon and thereby make an imprint upon the paper in line with the typewritten matter, will next be described. This appears more clearly in Figs. 7

' the printing blow to the type.

ness upon displacement of the type-sectors so that only when anamount key has been depressed in a bank will the tripping devices belonging to that bank be rendered operative, means being provided however for causing the automatic tripping of hammers belonging to unoperated banks to the right of the bank of highest denomination where a key has been operated, in order to provide for the necessary filling in of ciphers. In the present case the hammers 114 are formed on the forward ends of levers 115 which at theirrear ends are hung upon a pivot rod 116 at the back of the machine. Each of these hammer leversis formed with a depending prong 117 and with a curved horn 118 in rear of said prong whereby the hammer lever is given a bifurcated form below its pivot straight along one side which forms the rear edge of the prong 117 and curved in a semicircle at'the other side which forms the inner edge of the horn 118. A hammer driver cooperates with each hammer lever and comprises an upward extending curved arm 119'with a rounded end portion 120 bearing against the semicircular edge of the hammer lever bifurcation. The front edge of this arm 119 is curved for contact with the rear side of the prong 117 and in operation has a rocking engagement therewith so that the first movement of the hammer toward the type will be at considerably less speed than its final movement which imparts The hammer driver is formed with legs 121 and 122 which straddle a pivot rod 123. Springs 124: fastened to the lower extremities of the legs 121 and to the fixed framework of the machine tend to draw said legs rearwardly and consequently throw the arms 119 forward to actuate the hammers. Normally a crossrod 125 engaging with shoulders of the legs 121 holds the latter forward against the action of said springs. This cross-rod forms part of a restoring frame for the hammer drivers, said frame comprising side arms 128 pivoted upon a cross-rod or shaft 127, one of said side arms having a depending part 128 connected by a link 129 with a short crank arm 130 fastened to the shaft 1 1. When the operating handle 3 1 is drawn for ward and the shaft 4 1 consequently rocked this crank arm 130 moves rearwardly and in consequence the restoring frame is swung rearwardly so that the legs 121 of the hammer drivers are released from the restraining influence of said frame. However, the hind lo e 122 of said hammer drivers normally abut at their lower ends against shoulders of triggers 131 so that the retreat of the restoring frame alone willgnot permit the hammer drivers to act.

The triggers 131 are in the form of fingers pivoted on a crossrod 132 carried between side plates 133 pivoted at 13 1 to the frame of the machine. One of these side plates has a depending arm 135 connected by a link 136 with the lower arm of a lever 137 pivoted intermediate its ends to the frame of the machine and carrying at the upper end of its upper arm a roller 138 occupying a cam slot 139 in a depending portion 140 of the plate 60 heretofore described. The cam slotis of such contour that towardthe end of the forward movement of the operating handle 64 after the rearward swing of the rack restoring frame 535 i is over, the lever 137 will be vibrated so as to elevate the trig er-carrying frame 132133 thus carrying t e trigger supporting rod 132 to the dotted line position shown in Fig. 11. This of course results in elevating the rear ends of the triggers but does not result in freeing the hind legs 122 of the hammer drivers, the shouldered ends of the triggers simply rocking on the heels of these legs as illustrated in dotted lines in Fig. 11. In order to disengage the triggers from said heels it is proposed to establish fulcrums for the triggers intermediate their ends under control of the type-carriers. To this end each trigger is formed with a laterally projecting lip or flange 141 and there is mounted to swing upon the hammer driver pivot rod 123 a set of catches 142 in the form of levers with depending arms shouldered forengagementwith said laterally projecting lips or flanges 1-11. The upper arms of these levers are rounded as shown at 143 normally occupying similar shaped notches 14 1 in the under edges of rearward extensions 1% of the type-sectors. Spiral springs 1 15 connecting the triggers 131 with rearwardly projecting prongs 146 of the catch levers operate to press the triggers upwardly into engagement with the hammer drivers and to hold the lower arms of the catch levers away from the laterally projecting lips 1 11 of the triggers. W hen a type-sector is swung forward by reason of an operation of the machine key has been depressed in the bani: to which that type-sector belongs, the camming action of the curved edge of the notch 14:4? against the rounding head 1 13 of t e catch lever has the effect of swinging the lower arm of said lever rearwardly until its shoulder is positioned over the front edge of the laterally projecting lip 141 of the associated trigger 131. Under these conditions the rocking of the frame 132133 causes the trigger to rock upon the shoulder of the catch arm as a fulcrum so that instead of the trigger rising to the dotted line position shown in Fig. 11 its front end will be de as its rear end is elevated and will t' us become disengaged from the hind l hammer driver whereupon the 1 act under the influence of its spung 12 to drive the hammer against the type.

in order to provide for displacing triggers to the right of the highest denominational bank used for setting up an amount, notwithstanding no keys may have been depressed in banks belonging to thosetriggers to the" right, the material of the triggers is struck up beneath the lips or flanges 141 so as to form tangs 147 as shown in Fig. 12 PIOJQCting on the opposite sides of the triggers to 1 those sides from which the said lips project;

'llhus the tang of one trigger lies beneath the lateral-1y rO ectinfg trigger. it there ore no key has cen depressed in a bank to the right of one n which a key has been depressed, so that in this unoperated' bank to the right the catch lever 142 remains in its inefiective pos tion, nevertheless the trigger will be rocked on the middle fulcrum and the hammer driver released because of the laterally projecting 11p of the next trigger to the left overlying the tang 1 47 of the: unope'rated bank whereby this trigger is likewise held from upward movement at its middle and compelled to rock about a central fulcrum. In this manner the necessary ciphers will be printed in the decimal spaces to the ri ht of the highest denominational digit w ere the amount is not made up entirely of digital numbers.

In order to insure alinement of the amount types the rearward extensions 144 of the type sectors' have their rear edges scallo ed as shown at 148' forming notches space" apart the distance that the type are spaced apart. A comb 149 is arrange with its tines extending between the type-sector extensions so as to properly guide the same andthis' comb is carried u on a pair of arms 1 5i) pivotedon across re' 151, one of said side arms having a downward and forward extension 152 with a roller 153 occupying a cam slot 154 in an upwardextension or one of the side plates 13.3 of thetrigger carrying name; it will be remembered that the said frame is not moved until after' the type have been. positioned.- lts movement then produces a forward rocking of the comb frame whereby those portions of; the comb at the bases of the tines thereof are caused to enterthe notches 148 which correspond with the particular type in position to print. In this manner the alinement or the ty e is insured.

As to indicating and re 'st-ering or adding mechanism it will be su cient to state that the Wheels 4 carry pinions 4 adapted to cooperate with the racks 47. If indicating merely is desired the inions will remain constantly in mesh wit the racks. lif accunni'lating is to be accomplished then the pinions wrtl' be moved into and out otmesh with the racks and suitable means will be employed toregulate the periods of engagement and disengagement so that either ac-,.

cumulating, subtotal printinv or grand total printing can be a'ccom' l" bed after the manlip of the nei hboring machine.

nor of the well known Burroughs adding It is not proposed to enter into the details of mechanism which may be employed to accomplish these results because the present invention does not have neces-' sary correlation with accumulating or total printing ,instrumentalities. Y

It is of course to be understood that the invention is not limited to the partici-ll'ar form of embodiment here chosen for purposes of illustration and detailed description and that while certain well known typewriter and adding machine arrangements have been selected for the purpose of fully disclosing a complete organization whereby the invention can be practiced yet there are many other types of typewriter and adding machine arrangements which could equally well be utilized in carrying out said invention.
